API 613 spur gearboxes adapted and technically enhanced to meet the highest requirements; instruments and documentation suitable for specifications in the field of oil and gas engineering.

The turbo gearbox of the TA..XI type is based on a single-stage gearbox concept for high-speed applications with variable center distances and housing widths, which are optimized precisely according to the respective applications. These gearboxes are primarily used in the oil and gas industry as well as in the field of energy production. This range holds the world record as the most powerful gearbox in the turbo gearbox market with an output of 140 MW. They are designed according to API, AGMA, ISO, and DIN and set the standard for turbo gearbox technology in terms of quality, efficiency, and availability.
